JOHN NEWLOVE, OF MICHIGAN CITY, NDIANA,

STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 469,030, dated February16, 1892.

Application filed .Tuly 11, 1891.

To call whom it may concern:

Be it known that I, JOHN NEWLOVE, a citizen of the United States,residing at Michigan City, in the county of La Porte and State ofIndiana, have invented certain new and useful Improvements inStreet-Sweepers; and I do hereby declare that the following is a full,clear and exact description of the same, reference being had to theanneXed drawings, making a part of this specification, and to theletters of reference marked thereon.

This invention relates to certain new and useful improvements instreet-sweeping machines, and is designedmore especially as animprovement upon the construction shown in my patent, No. 433 538, datedAugust 5,1890.

I have reversed the machine, applying the draft at the end farthest fromthe brush and delivering the dirt into a receptacle at the forward end,so as to throw the weight nearer the front.

I provide improved means for elevating the brush from the ground and'for actuating an apron which I arrange between the brush and elevator.I arrange to elevate both the brush and apron sinultaneously by simplemeans. This apron or dustpan is arranged so that its lower edge drags onthe ground, while its upper edge vibrates on a rod.

I provide an improved brush, which may or may not be provided with steelfingers, the brushes being carried by springhooks or rings, which permitthe brushes to readily adapt' themselves to any inequalities in theground or pavement over which the machine is traveling.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims. v

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon,form a part of thisspecification, and in which-` Figure 1 is a side elevation of myimproved machine with a portion broken away. Fig. 2 is a verticallongitudinal section through the same. Fig. 2 is a vertical section onthe line .e z of Fig. 2. Fig. 3 is a side elevation from the reverseside to Fig. l. Figat is a top plan seen' from Fg. 2;

with portiors broken away. Fig. 5 is a detail of a portion of thebrush-cylinder.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by lette-,A design-ates themain body or case of the machine, which is provided with two hingedcovers A' and A'asuitable crosspiece a being provided to form a supportfor the adjacent edges of the two doors, as seen in Fig. 2. Totheforward end of themain body or case there is attached in any suitablemanner a cross-piece a in which is swiveled the vertical pin a whichearries at its lower end the front guide-whe`el A and to the upper endof which is attached the tongue or pole A as seen best in Figs. l and 2.The cross-piece a' is secured to the body at a slight distance above thelower edge thereot', and the lower front edge of the case or body is cutaway, as shown at a, as seen in Fig. 2, to provide for the setting ,ofthe guide-wheel close to the case and provide room for the guide-wheelto work, as seen in Figs. 1 and. 2, by which means a square 'corner maybe turned, if desired. The cross-piece a' may be braced byinclinedbraces a asshown in Figs.

l and 2, if desired. i

B is the dirt-receptacle. It is arranged at the forward end of thecas'ewithin the latter, and its bottom' inclnes in opposite directionsfrom a lon-gitudinal center toward each side, as seen best in Fig. 4:,being provided at each side with a hinged door B', one of which is shownup in Fig. 1. Any suitable means may beprovided for holding the doorsopen, if desired. v

C is an elevator eonsisting of an endless band or belt carried over: thedrums or rollers c and being provided upon its outer surface withcross-slats c', as shown best in Fig. 2. This elevator is' arranged inan inclined position, as seen in Fig. 2, and is designed to re: ceivethe dirt fro m the apron or dust-pan upon which it is brushed by thebrushes, as will be The pintles of the rollers c are journaled inelongated Slots '0 in the walls of the case, as seen in Fg. 1, and areadapted to be adjusted, when necessary, by the arms O', which arescrew-threaded at one IOO 4 ri-al, to the outer faces ofwhi-chareatt'ached i end and passed through eyebolts 0 on the sides of thecase and provided with nuts 0 for adjusting them, the arms beingconnected with the pintles of the rollers in a manner similar to theeorresponding Construction in my prior patent and Operating in the sameway.

Dis the main aXle, carrying the main wheels D' and` suitably journaledin the walls of the E' is a pulley on the s-hafit of the uzpper rollerof the-eleVa-tor, and E is an idler* on a stub-shaft upon the: same'side of the case and in proxin ity thereto, as seen best in Fig. E is arpu l l'ey'on the'shaft of the bru'sh-cylind -er, and over this p-ulley,over the pulley' (1 u n-der the: idler' E over the idler E and under thepu 'lley E' passes the cndless belt F, asshown in Figs. 3 and 4, so thatmotion isi-nparted to the brush-shaft and` to the elevater.

Gr is the brush-shaft. It is su itably journaled invertically-adjustable bearings g, as seen bes-t in Fig. 1, and on thisshat't' are the heads G", which are provided with radial groovesg', asseen best inFigs. 2 and 5', in which arearranged the rods g?, as see-nbest inFig 5, and around which are the-springs 9 H are rings of somesuitable springy mate-` in an y suitable man ner the bars G which Carrythe brushes g, the' end s of the bars being-"provided with offsets andarranged in` theradial grooves of the heads,as seen in Fig. 5. ThisConstruction provides for the holding of the brushes te their work andyet allows them to-yiel'd when passing? over ob-- structons'.Spring-plates H' for adding` stiffness to' the: brushes may be provided,if d'esired, uponthe bars, as seen` in Fig. 2' and by dotted lines inFig.. 5, being preferably alternately'arranged, as shown in Fig. 2. Whenforus'e upon asphalt pavement, these fin-gers are preferably omi'tted.The bars Gr are preferably each fol-med in two parts separated at thecenter, as seen in Fig. 5, so as to allow one part to yield independentof the other.

I is a cross-bar provided with fingers t' to Work between the brushes tokeep them from becoming clogged up.

J isa dust pan or apron arranged between the elevator and brush, with'its upper end carried by a pivot or rod j and its lower end: ar-

` seen best in Fig. l.

ranged to contact with the ground, as seen in Figs. 1 and 2. It isdesigned to be'elevated from the ground when desired. v

In order to elevate the brush-cylinder and the dust-pan from the groundwhen desired,I

t provide the mechanisn shown in Figs. 1 and 4, in which K is a chain orrope or cord attached at one end to the dust-pan, as at j', and itsother end, after passing over the pulley K', is fast to a drum L,carried by a suitable shaft at the forward end of -the case, as M isanother chain, cord, or rope attaehed at one end to the hearing of thebrush-shaft 'and at its other end to a pnlley m, as seen in Fg. l.nec'ted to an arni. N', fast' on the shaft of the pulley m, and its.other end attached to` the drum L as; seen in Fig.` l. The drum isprovided: with a. ratchet-Wheel 0 and with a lever 'O and pawls 0', asseen` in Fig; l. The shafit of the pulley m extends to the oppositesideof the case` and carri-'es a' like: pu'l l'ey m connected by cord mwith. thebear-ingof the brush-shaftupon that side, as seen.- in Fig. 3,s'o that by manipulation of' the lever O the brush and thed usvpan Willbe siinultaneously raised When d'esi red.

Modificatio'ns in detail may be res'o-'ted to without (leparting frornthe: spirit of the in vention or' sacrificing any ot'` its. advantages.

What I claim as new i s- 1. In a cylindricalbrus l, the combination,with the heads having rad i al grooves, ot' the shaft, the, spring-heldbars G paral lel with the-s-haft,t'he s-pring-bandsdiseonnected from theshaft and carrying said bars, and. the brushes carried by' said bars, assetfo'th,

2. In a cylind-rical brush thecombination, with the heads having, 'adial grco-ves, of' the' shaft, the spring-held bars G. parall'el' withthe shaft, the spring-bands d-iscon'nected from the shaft and carryingsaid bars, the. brushes carried bythe bars, and. the spring-plates onthe bars parallel with the brushes, substantially as 'and for thepurposespecified The combination, with the heads' having radial grooves, theshaft, the rods arran'ged in the grooves, the springs around saidrod's',.the bars parallel with the shat't'and having oltsets at' theendsand sleeved on the said: rods the spring-bands, and the brushes carriedby said bars, all substantially as shown and d'escribed.

In testimony thatIelaim the aboveI have hereunto subseribed my name inthe presence of two witnesses.
